Specification forming part of Letters Patent No. 198,932, dated JanuaryOctober 3, 1877'. y

8, 1878; application lfiled To all whom it may concer/n.-

ABe it known that we, WILLIAM E. E D- WARDs, 4of vthe city of Oakland,county of Alameda, and FRANK J; GEAGIER, of the city and'fcounty of SanFrancisco, both in the State of California, have made and invented anewand useful Improvement in Bellows- Nozzles, which invention is fully setforth in the following specification and accompanying drawing. .A t 1 Inthe said drawing, Figure l is aperspective view of the head of a bellowswith our invention'applied thereto, and with the nozzle detached. Fig. 2is a plan view of the head of the bellows with the nozzle removed. Fig.3 is a sectional view of the inner rings through the line w. w, Fig. 2.Fig. 4is a sectional view of the saine through the line y y. Figs. 5and- 6 are views of our improvednozzle, the same being an end and a sideview, respectively.

Our invention has for its object to provide a better means for placingand securing the nozzle within and upon the head of a bellows withoutthe use of screws or bolts; and in such a manner is our inventionconstructed that the nozzle, when] loosened, may be set up and 4hold theend of the nozzle, the exterior surface `of ile .nozzle at this pointbeing provided wipl lugs or projections, which engage and wolf1 beneaththe threads within the sleeve, Whreby the end Vof the `nozzle is, by theaction t these threads, drawn against the head and l'ld firmly in place.u

In the afmpanying drawing, Fig. l shows the end Ol.' -id of a bellows ofthe ordinary constructionvithin which is applied our improved slevnrferrule c. rllhis sleeve its within and s"ounds the opening formed in Y4-this end within the opening the lugs will, by

a turn of the nozzle, be brought beneath these segments, and, by virtueof their inclination, the nozzle will be drawn and held down tightly toits seat against the head.

The screw-thread segments b 1) lare placed at opposite sides in the ringc, so that one en gages 011e lug, B, and the other one the lugB. Thisshorter end of the nozzle is not in contact with the interior of thecylinder or sleeve a, exceptat the points where the lugs B touch,

and a space is left between the parts, which the air fills, and thuskeeps the parts of the head from becoming unduly heated by the nozzle.These lugs could be replaced by a screw thread or segment, which wouldhold the nozzle equally as secure; but Amore of the nozzle would thus bebrought in contact with the ring u, and for this reason I prefer theconstruction shown.

' The nozzle A has a flange, c, at proper distance from the end that isplaced within the nozzle ring or sleeve, and a collar, d, behind it, ofthe same size as the inside circumference of the rin g, which fitstightly within it when the nozzle is locked in position, at which timethe flange c is brought down and held against the edge of the ring yandthe wood surrounding it, and thus the escape of the air :from betweenthe head and the nozzle is prevented.

As thus constructed and applied, our invention removes all necessity ofplugging up the wood in the head of the bellows to tighten the screws orbolts now employed to hold the nozzle in place, for, the end grain ofthe wood being presented at the head of the bellows, the screws are notheldflrmly withinit, and the nozzle soon works loose; butin ourinannerof con structing thehead the wood,when onceproperly wedged up betweenthe outer and inner rings or ferrules, is not weakened or broken by theintroduction of screws, and the inner ring is kept tightly in place.

The nozzle A has a projecting nib or ear, c, on the flange, to allow thenozzleto be set up, whenever it becomes loosened, by the use of ahammer, a few blows being all that is required to tighten it 5 and thenozzle is likewise provided with a lug, B", in front ofthe flange, toserve as a locking device to hold the nozzle in place on the bellowswhen it is reversed, and its longer end is inserted within the openingin the head, for purposes of transportation and shipment. In thisposition the lug B" engages with and works beneath the screw-segments.

Having thus fully described our invention, what we claim as new therein,and desire to se cure by Letters Patent, is

41. A self-locking and removable nozzle for bellows, provided withlocking-lugs B B', and ange and collar c and d, and combined and adaptedtobeused witha ring, ferrule, or other equivalent device, which isinserted and xed within the opening in the bellows-head, and which isprovided with segments of a screwthread, to engage and hold the lugs BB', substantially as herein described and specified.

2. In combination with a bellows, the ring or sleeve a, fixed within theopening in the head, and provided with separate segments of ascrew-thread, which `are adapted to engage with and hold the lugs orprojections formed upon the larger end of the nozzle, the same beingconstructed, for this purpose, substantially as herein described andspecified, whereby the use of screws or bolts is dispensed with.

3. A bellows-nozzle constructed, substantially as herein described, withthe lugs or projections B B B", and the flange and col-` lar c and d,and the nib or ear e, combined and usedl in connection with the ring orferrule ia, formed as described, and fixed within the opening in thebellows-head.

v 4. In combination with a ring or ferrule, a, iixed within the openingin the head lof a bellows, and provided with separate segments of ascrew -thread, as described, the nozzle A, having its larger end of lessdiameter than the size of the ring or ferrule, and provided with lugs BB upon this end, whereby, when the nozzle is inserted and locked withinthe head, an airspace will be left between these metal parts, except atthe points where the lugs B Bl touch the surface of the ring or ferrule,as herein described, for the purpose set forth.

In testimony that we claim the foregoing we have hereunto s et our handsand seals this 1st day of September, 187 7 WILLIAM E. EDWARDS. L. s.] vFRANK J. GBAOIER.. L. s.| Witnesses:
